Hero Hack: Reversing Heroes and Raising Harem

Zain's eyes slowly opened. His nose twitched. "…Smells good."

He sat up, stretched once, and followed the scent to the hall.

A huge pot sat on the table, steam rolling out of it.

Inside, he saw thick soup with chunks of meat floating on top.

Zelia looked up and smiled. "Zain, you're awake. I've prepared food for you."

"This is bird devil soup. Eat it while it's hot. There's more coming after this."

Zain stepped closer, inhaling the aroma. "Smells amazing, big sister."

"Of course," Zelia said with a small laugh. "I made it myself."

He grabbed the spoon, took a sip, and his eyes widened. "Wow… delicious."

Zelia smirked. "Naturally. You think I'd serve you something bad?"

Instead of sipping slowly, Zain lifted the pot with both hands and drank straight from it.

The hot broth and meat slid down his throat, and his [Heavenly Demon God] ability instantly went to work, converting it all into [Heavenly Demon Ether].

The toxins and corrosive ether inside the devil meat also didn't harm him.

Instead, they gave the soup a unique, rich taste only he could enjoy.

Velra leaned on the wall, watching. "Still a monster when it comes to eating."

Savra crossed her arms. "At least the food's going to the right place. Look at him. He's already recovering."

Zain finished the entire pot in seconds and set it down with a satisfied exhale. "Perfect. Big sister's cooking… unbeatable."

Zelia chuckled and shook her head. "You flatter me too much."

Savra grinned. "As expected of the Heavenly Demon."

Zain wiped his mouth and leaned back in his chair. "Now that I've got enough energy… Savra, do you want to change now?"

Savra paused, tilting her head. "Already? Are you sure you're fully recovered? Maybe you should eat a bit more first."

Zain grinned. "Don't worry about me. I can regain my energy easily once I eat the second course."

"Just tell me now, what kind of abilities do you want?"

Savra thought for a moment, then nodded. "It's simple. Something connected to flame."

Zain raised an eyebrow. "That's it? Just flame?"

Savra shrugged. "I'm already used to wielding fire. I don't need anything else. Just make it stronger than before."

Zain smirked. "Alright then. Simple request… but I'll make it far more powerful than you expect."

Velra leaned against the wall, crossing her arms. "Oh, this will be fun to watch."

Zelia glanced at Savra with a small smile. "Looks like it's your turn now."

Savra smirked. "Yeah… and Zelia, you'd better start thinking about your choice. Are you going to become Zain's slave or not?"

Zain chuckled softly at the remark. "Don't pressure her too much. Big sister can take her time."

Zelia nodded slightly, her eyes fixed on the scene. "I'll watch first… then decide."

---

Zain opened his system interface, scanning through the menus.

"Velra's title is Velvet Demon," he muttered. "So for Savra… let's go with Infernal Demon."

A notification blinked across the screen:

[Member Registered: Savra Svarokh]

[Collar Created: Infernal Demon Collar]

[Proceed with Ability Creation?]

Zain's smirk widened. "Of course."

He started with her main ability, deciding it should be like Velra's and his.

Something that boosted her body and sustained her power endlessly.

[Ability Created: Infernal Demon God]

[Effect: Absorbs any form of energy and converts it into Infernal Demon Ether, constantly strengthening the body and fueling other abilities.]

"Now for the special ether…" Zain tapped through the options.

"It needs to be flame-based, corrosive flames that can burn both body and soul."

"It should also allow her to create weapons, cast any kind of flame spell, and coat herself for stronger physical attacks."

Then, an extra idea hit him. "Let's make it interesting… every hit she lands should leave a mark that makes the enemy take more damage."

[Ability Created: Infernal Demon Ether]

[Effect: Produces corrosive flames that burn body and soul. Can form weapons, cast flame attacks, and coat the body to boost attacks. Enemies hit gain Infernal Mark, causing burning over time and extra damage.]

Zain leaned back slightly, satisfied. "Now the domain…"

He compared it to Velra's. "If Velra's domain increases sensitivity, Savra's should instantly mark everyone in range."

"The more marks she stacks, the stronger she becomes."

[Ability Created: Infernal Demon Zone]

[Effect: Creates a domain that instantly marks all enemies with Infernal Mark and burns them. More marks make Savra stronger and her attacks deadlier.]

Zain's eyes stayed on the system screen for a moment longer before he finally closed it.

"Perfect," he said, his voice low.

"You're basically a walking inferno now, Savra. Every bit of energy you take in will become your own destructive ether."

"Any enemy who survives your first strike will be marked, and those marks will make you even stronger."

"In a crowd fight… the moment your domain appears, everyone burns."

A slow grin tugged at his lips. "Good… really good."

The moment he finished, a flash of light appeared in his hand.

A brand-new collar rested in his palm, sleek black with a faint glow of fiery orange-red lines.

He stepped toward her, holding it out. "This will be your collar. When you wear it, your new abilities will become part of you."

"But… the moment you put it on, you'll officially be my slave."

Savra tilted her head, then laughed softly. "I already told you before, Zain. I'm already your slave."

Without hesitation, she took the collar and fastened it around her neck.

The moment it clicked into place, her clothes dissolved into ash just like Velra's had.

Savra caught Zain's gaze lingering on her bare form and smirked.

"A bit kinky, aren't you? Making a collar that instantly destroys my clothes?"

Zain's smirk matched hers. "Don't think too much about it."

"The collar removes them to replace them with something better, more durable, flexible, and perfectly fitted."

Savra raised a brow. "You could've done that without stripping me first."

"Not really," Zain replied with a small shrug.

"It needs to cover every inch of your real body for a perfect fit. And besides…"

His eyes glinted, "…it's not exactly unpleasant to see you like this."

Savra gave him a playful smile. "Pervert."

In the next instant, her body was wrapped in a black bodysuit with glowing orange-red lines tracing along her curves.

A matching short jacket appeared over it, sleek and futuristic, much like Velra's but with a fiery theme unique to her.

Zain's eyes flicked over her new attire. "Feels good, doesn't it?"

Savra looked down at herself, flexed her fingers, and smirked. "Yeah… it feels quite good."
